/**
 * Defines transforms for reading and writing common storage formats, including
 * {@link com.google.cloud.dataflow.sdk.io.AvroIO},
 * {@link com.google.cloud.dataflow.sdk.io.BigQueryIO}, and
 * {@link com.google.cloud.dataflow.sdk.io.TextIO}.
 *
 * The classes in this package provide {@code Read} transforms that create PCollections
 * from existing storage:
 * 
{@code
 * PCollection inputData = pipeline.apply(
 *     BigQueryIO.Read.named("Read")
 *                    .from("clouddataflow-readonly:samples.weather_stations");
 * }
 * and {@code Write} transforms that persist PCollections to external storage:
 *  {@code
 * PCollection numbers = ...;
 * numbers.apply(TextIO.Write.named("WriteNumbers")
 *                           .to("gs://my_bucket/path/to/numbers"));
 * }
